Bug Description
[Impact]
Pericom EHCI/OHCI USB Controller can't detect hotplug event when it's runtime-suspended, due to its unreliable PME#.
[Fix]
Disable PME for all its power state since all of them don't work reliably.
[Test]
Hotplugging event can be reliably detected by the device, after the fix gets applied.
[Regression Potentia]
Low. This targets specific device, without touching any logic.
